6. Evidence for Lake Turkana in Africa is the best at showing what?
- Living fossils
- Genetic drift
- Punctuated evolution
- Natural selection
- Gradualism
7. Measuring changes in the SIZE and SHAPE of fossils is a way of monitoring what?
- Rates of evolution
- Gradualism
- Natural selection
- Genetic drift
8. What are living fossils?
- Species that remain virtually unchanged for millions of years
- Fossils which fully preserve the organism, including organs and hairs
- Animals that are partially related to fossilised organisms
9. Fossil measurements must be expressed as what?
10. Who are at greater risk of extinction?
11. Long periods of no evolutionary change are PUNCTUATED by rapid evolution when SPECIATION occurs is the theory of what?
- Natural selection
- Punctuated equilibrium
- Gradualism
12. The result of an complete fossil record - intermediates were very common
13. Most fossil records don’t reflect gradualism
14. 'Evolution of reproductive isolation' is a definition for what?
- Gradualism
- Microevolution
- Speciation
- Macroevolution
15. Punctuated evolution may occur because...
- Small isolated populations evolve rapidly
- All of the above
- New species arise by splitting off from lineages
- Sub-population gives rise to new species
- New species originates in a very small part of ancestral range so fossils are rare
16. Does evolution appears to occur at different rates?
17. 'Change in gene frequencies' is the definition for what?
- Gradualism
- Macroevolution
- Microevolution
- Speciation
18. Westoll (1949) studied the evolution of what?
- Trilobites
- Lung fish
- Horse teeth
- Worms
19. Lampetra is an example of what?
- A living fossil
- An evolutionary change
- Natural selection
20. 'Patterns in change of species composition over geological time periods' is a definition for what?
- Speciation
- Gradualism
- Macroevolution
- Microevolution
